BACKGROUND

Age-restricted materials are sold at many points of sale. Many points of sale do not have proper procedures in place for restricting access to users who are too young to consume the age-restricted material. Identification cards, such as government issued identification cards, increasingly include some form of machine-readable data. Often many different entities (e.g., corporations, states, or government organizations) use different encoding for this machine-readable data.

Illustrative Example of a Device for Point of Sale Age Verification

Turning now to FIG. 1, which shows one illustrative embodiment of the present disclosure 100. As shown in FIG. 1, the system 100 comprises an identification card 102, and internet enabled device 106, and a point of sale 118. The point of sale 118 comprises age-restricted material 116, such as an electronic cigarette (e-cigarette), which are sometimes referred to as vaping devices. An e-cigarette dispenses a vapor that contains nicotine, and which a user inhales. An e-cigarette is not authorized for use for people under the age of eighteen. In other embodiments, age-restricted material may comprise, e.g., a tobacco product, an electronic cigarette, an alcohol product, a firearm, ammunition, explosives, pornography, gambling, or lottery tickets. Embodiments disclosed herein provide systems and methods for restricting the sale of age-rest restricted material 116 to unauthorized users (e.g., user's below a designated age such as 18 or 21 years of age).

The illustrative embodiment further comprises an internet enabled device 106 (e.g., a wearable device, smartphone, tablet, portable music device, kiosk, desktop, or laptop). In the embodiment shown in FIG. 1, the internet enabled device 106 comprises a scanner 108 for reading data from an identification card 102 comprising a passive data source 104. In some embodiments, the identification card may include, e.g., a State Issued Driver License, State Issued Real ID Compliant Driver License, State issued identification card, Federally issued Passport or Military Identification. In some embodiments, the identification card 102 may comprise an electronic identification card, e.g., an electronic ID stored in an application on a mobile device such as a smartphone. In some embodiments, such an electronic identification may comply with ISO/IEC CD 18013-5. For example, some governments or other entities may issue an electronic identification that the user stores in a mobile wallet application. Thus, in some embodiments, the identification card 102 and the internet enabled device 106 may comprise a single device, e.g., a mobile device comprising an electronic identification card.

In the embodiment shown in FIG. 1, the scanner 108 comprises a digital camera configured to capture images. In the illustrative embodiment, this camera comprises a standard camera found on mobile devices, without any specialized hardware. The illustrative embodiment further comprises a network connection, such as a wired or wireless internet connection. The illustrative embodiment further comprises a network interface 110 (e.g., Bluetooth, Near Field Communication (“NFC”), or RFID) to connect to a similar network interface 114 on the point of sale device 112.

In the illustrative embodiment, the user accesses an application configured to verify the user's age by capturing an image of the user's identification card 102. For example, the user captures an image of either the front or back face of a driver's license. For example, the user may load a mobile application that includes a widget to execute an age-verification application. In such an embodiment, this widget may appear as a button, switch, graphical user interface, or other user interface available for use with the mobile application. After the user accesses this functionality, e.g., by interacting with the widget, the internet enabled device 106 may be configured to enter an image capture mode. Alternatively, the user may access a web browser and upload a picture of the identification card 102 via a website accessed through the web browser.

In the image-capture mode, the internet enabled device 106 may access a digital camera coupled to the mobile device and display the output on a display of the internet enabled device 106. The user may then direct the camera toward the user's identification card 102 (such as a driver's license). Specifically, the user may direct the camera toward passive data source 104, which may comprise machine-readable data (e.g., a barcode encoded in PDF-417 appearing on the back of the identification card). Examples of PDF-417 are shown in FIGS. 4A and 4B below. When the camera captures an image of the machine-readable data at sufficient resolution to extract the data encoded therein, the application may exit the image capture screen, and return to another screen of the mobile application.

Once the image has been captured, a processor on the internet enabled device 106 may process the image to extract encoded data. In some embodiments, this processing may comprise cropping and compressing the data contained on the image. The internet enabled device 106 may then use a network interface (e.g., a wired or wireless network interface) to transmit the image data to a server.

In some embodiments, the server may comprise algorithms developed to quickly process and determine information associated with the cards. In some embodiments, these algorithms may have been developed utilizing a database of data associated with identification cards. Currently, in the United States, there are more than 1,000 different formats of encoded data associated with identification cards issued by various entities (e.g., corporations, states, government organizations, military, or post office). For example, some states change the encoding used on their drivers licenses every few years. However, those states may leave the older drivers licenses in rotation. Thus, these identification cards may comprise out of date encoding. Further, some states may use multiple different types of encryption. Similarly, multiple states use different encoding and encryption, thus, an algorithm associated with, e.g., Georgia may not be useful for decoding data associated with another state's identification cards. In some embodiments, the remote database may comprise data associated with a large number of these entities. Algorithms developed based on the data in this database may enable the server to quickly process and parse the data on an identification card. Further, in some other embodiments, data comparison software or string searches may enable the database to be quickly searched to determine information about the received data.

Further, in some embodiments, the server may determine whether the identification card is valid or “fake,” e.g., by comparing extracted data to a database of valid identification cards. Further, the server may track whether the user has recently activated or purchased other age-restricted material or purchased more than a certain amount of age-restricted material (e.g., more than a specified number of e-cigarette devices) in a specified period. In still other embodiments, the server may be configured to compare information associated with the user to a no sell list. If the user is on the no sell list the server may send information to the internet enabled device 106 to prevent the internet enabled device 106 from authorizing purchase of age-restricted material 116.

Once the data is decoded, the server may use a network connection to transmit the decoded data back to the internet enabled device 106. This data may include, e.g., the user's date of birth, a first name, a last name, an address, a city, a state, a zip code, an issue date, or an expiration date, and may further include information accessed from a purchase history database, e.g., the last time the user bought age-restricted material 116, the prior quantities of age-restricted material 116 bought by the user, and/or whether the user has recently activated an age-restricted device. In other embodiments, this information may be a simple authorization code indicating that the user is authorized to complete the transaction. This information is then used to confirm that the user is authorized to purchase age-restricted material 116. If the user is authorized to purchase the age-restricted material, the Internet enabled device 106 will transmit a verification signal to the point of sale device 112. The point of sale device 112 is programmed to not authorize sale of the age-restricted material 116 without the authorization signal. In one embodiment transmitting the verification signal may comprise displaying a second passive data source comprising a verification code and configured to be scanned by the point of sale device 112. In another embodiment transmitting the verification signal may comprise displaying a textual verification code configured to be entered by a user into the point of sale device 112. In still another embodiment, transmitting the verification signal may comprise transmitting a verification signal to the point of sale device 112 network interfaces 110 and 114, e.g., via wired or wireless data transmission.

This illustrative embodiment is mentioned not to limit or define the limits of the present subject matter, but to provide an example to aid understanding thereof. Illustrative embodiments are discussed in the Detailed Description, and further description is provided there. Advantages offered by various embodiments may be further understood by examining this specification and/or by practicing one or more embodiments of the claimed subject matter.

Illustrative Systems for Point of Sale Age Verification

FIG. 2A shows an illustrative system 200 for point of sale age verification. Particularly, in this example, system 200 comprises a computing device 201 such as, e.g., a wearable device, smartphone, tablet, portable music device, laptop, desktop, kiosk, or dedicated computer terminal. As shown in FIG. 2A, computing device 201 has one or more processor(s) 202 interfaced with other hardware via bus 206. A memory 204, which can comprise any suitable tangible (and non-transitory) computer-readable medium such as RAM, ROM, EEPROM, or the like, embodies program components that configure operation of the computing device. In this example, computing device 201 further includes one or more network interface devices 210, input/output (I/O) interface components 212, and additional storage 214.

Network device 210 can represent one or more of any components that facilitate a network connection. Examples include, but are not limited to, wired interfaces such as Ethernet, USB, IEEE 1394, and/or wireless interfaces such as IEEE 802.11, Bluetooth, Near Field Communication, RFID, and/or radio interfaces for accessing cellular telephone networks (e.g., transceiver/antenna for accessing a CDMA, GSM, UMTS, or other mobile communications network(s)).

I/O components 212 may be used to facilitate connection to devices such as one or more user interfaces 216 (e.g., keyboards, mice, speakers, microphones, and/or other hardware used to input data or output data) and display 220 (e.g., a display such as a plasma, liquid crystal display (LCD), electronic paper, cathode ray tube (CRT), light emitting diode (LED), or some other type of display known in the art). In some embodiments, user interfaces 216 and display 220 may comprise a single component, e.g., a touch screen display. In some embodiments, I/O components 212 may include speakers configured to play audio signals provided by processor 202. Storage 214 represents nonvolatile storage such as magnetic, optical, or other storage media.

Scanner 218 comprises a sensor configured to detect a passive data-source, such as data encoded in a multidimensional code. For example, in one embodiment, scanner 218 may comprise an optical sensor such as a digital camera. In such an embodiment, processor 202 may use scanner 218 to take an image of a passive data-source, e.g., a matrix barcode such as a QR code, bar code, or multidimensional bar code encoded in PDF-417. In some embodiments, the digital camera may comprise no specialized hardware capability, for example, in some embodiments, the digital camera may be a standard digital camera found on mobile devices such as smartphones and tablets. Further, in some embodiments, the digital camera may comprise an auto-focus capability that enables the camera to capture an image of the multidimensional code at sufficient resolution to reliably extract the encoded data. In such an embodiment, processor 202 may use software stored in memory 204 (discussed below) to determine data encoded in the multidimensional bar code. In other embodiments, scanner 218 may comprise another component, such as a laser scanner, CCD, reader, video camera reader, or other type of scanner configured to scan a passive data-source such as a multidimensional bar code. In still other embodiments, scanner 218 may comprise a scanner configured to detect data from a magnetic code (e.g., a magnetic strip), an RFID, NFC, a SmartCard, an Integrated Circuit Card (ICC) or some other type of passive data.

Turning to memory 204, exemplary program components 224 and 226 are depicted to illustrate how a device may be configured to decode data on identification cards. In this example, an image detection module 224 configures processor 202 to monitor the input from scanner 218 to detect an image comprising machine-readable data. For example, module 224 may configure processor 202 to enter an image capture mode in which display 220 shows the output from scanner 218. Further, in some embodiments, image detection module 224 may be configured to determine the quality of data received from scanner 218. For example, in one embodiment, this may comprise measuring the resolution and focus of the received image. In some embodiments, image detection module 224 may further comprise software to enable processor 202 to determine that the image is of sufficient quality, and therefore capture the image.

Image-parsing module 226 represents a program component that analyzes image data received from scanner 218. In one embodiment, image-parsing module 226 may comprise software configured to enable processor 202 to crop and/or compress the captured image for transmission via network 210 to a remote server. In further embodiments, image-parsing module 226 may comprise program components configured to enable processor 202 to perform an image comparison between the captured image and data stored on a local database. In some other embodiments, image-parsing module 226 may comprise algorithms that enable the processor 202 to quickly determine the data encoded in a label, e.g., the name, date of birth, address, driver's license number, height, weight, state, county, race, organ donor status, issue date, expiration date, driver restriction, class of vehicle, passport information, criminal record information, or any other information stored in the encoded data. In some embodiments, some of this information may be withheld, e.g., due to privacy concerns. Thus, in some embodiments, information such as a person's height, weight, race, organ donor status, driver restrictions, or class of vehicle may be withheld.

In other embodiments, program components 224 and 226 may be comprise software components configured to enable processor 202 to process other types of passive data-sources, e.g., magnetic strips, RFIDs, NFC, SmartCards, or Integrated Circuit Cards (ICC). In still other embodiments, components 224 and 226 may be configured to access and authenticate data associated with electronic identification cards, e.g., cards that comply with ISO/IEC CD 18013-5.

In other embodiments, computing device 201 may comprise additional components, such as motion detectors, accelerometers, or GPS receivers that processor 202 may use to determine other information, such as the movements or orientation of computing device 201.

Turning now to FIG. 2B, which shows an illustrative system 250 of an age-restricted device 251, e.g., an e-cigarette device. In some embodiments, the age-restricted material 116 discussed above with regard to FIG. 1, may comprise such an age-restricted device 251.

As shown in FIG. 2B, the system 250 has one or more processor(s) 252 interfaced with other hardware via bus 256, age-restricted material 254 (e.g., a nicotine or a cannabinoid such as THC or CBD containing substance, or some controlled medication (e.g., anxiety or depression medication), opioids, or some other controlled substance, which may be configured to be vaporized or otherwise dispensed by age-restricted device 251), a network interface 260, and input/output (I/O) interface components 262.

Network device 260 can represent one or more of any components that facilitate a network connection. Examples include, but are not limited to, wired interfaces such as Ethernet, USB, microUSB, Firewire, IEEE 1394, and/or wireless interfaces such as IEEE 802.11, Bluetooth, Near Field Communication, RFID, and/or radio interfaces for accessing cellular telephone networks (e.g., transceiver/antenna for accessing a CDMA, GSM, UMTS, or other mobile communications network(s)). In some embodiments, network interface 260 is configured to receive an activation signal from computing device 201, described above with regard to FIG. 2A, transmit this activation signal to processor(s) 252, which then activate the age-restricted device 251 based on the activation signal.

I/O components 262 may be used to facilitate connection to devices such as one or more user interfaces 266 (e.g., keyboards, mice, speakers, microphones, and/or other hardware used to input data or output data) and display 220 (e.g., a display such as a plasma, liquid crystal display (LCD), electronic paper, cathode ray tube (CRT), light emitting diode (LED), or some other type of display known in the art). In some embodiments, I/O components 262 may include speakers configured to play audio signals provided by processor 262.

FIG. 3 illustrates another illustrative system for point of sale age verification 300. As shown in FIG. 3, system 300 comprises a computing device 310, comprising a processor 311, memory 312 comprising instructions 313, and a network interface 314. In some embodiments, computing device 310, and its components may operate similarly to the components of computing device 201 described above with regard to FIG. 2A. Thus, in some embodiments, the components of computing device 310 may enable the computing device to scan a passive data-source, process the data, and transmit the processed data via access network 330.

In some embodiments the access network 330 may be a 3GPP network, a 3GPP2 network, a WiMAX network, 4G LTE, HSPA+, UMTS, a Wi-Fi network (e.g., a network that operates in accordance with an IEEE 802.11 standard), or some other wireless access network. In other embodiments, access network 330 may comprise a wired network such as Ethernet, USB, microUSB, Firewire, IEEE 1394, cable, or telephone networks. In some embodiments, access network 330 may comprise a plurality of different types of wired and/or wireless networks configured to transmit data between computing device 310 and server 320.

As shown in FIG. 3, the access network 330 is further coupled to a server 320. Server 320 is configured to receive data sent from computing device 310 via access network 330 using network interface 323. Network interface 323 may comprise a wired and/or wireless network interface configured to receive data using access network 330.

Server 320 further comprises a processor 321 coupled to a database 322. Database 322 may comprise a database of data associated with identification cards. In some embodiments, the database 322 may comprise data associated with identification cards issued by one or more of corporations, states, and government organizations. Processor 321 may be configured to use data comparison software to compare data received from computing device 310 to data stored in database 322 to determine the type of encoding associated with an image and then quickly decode the data, e.g., by parsing the data to determine the stored information, e.g., the name, date of birth, address, driver's license number, height, weight, state, county, or any other information stored in the encoded data.

In other embodiments, rather than performing a full lookup of database 322, processor 321 may instead comprise algorithms configured to determine information about a passive data source without having to search database 322. In some embodiments, these algorithms may have been developed using the data available in database 322. Further, in some embodiments, these algorithms may enable the processor 321 to quickly determine the jurisdiction that issued a card, e.g., by determining the Issuer Identification Number (“TIN Number”) associated with the card, or the type of encryption used in the card. Once this is determined, processor 321 may access an algorithm associated with that IIN number to quickly determine data associated with the passive data source. In some embodiments, processor 321 may be configured to determine the stored data in 2 seconds or less. Processor 321 may also be configured to determine that a passive data source is associated with a valid identification card, e.g., by confirming that extracted data matches data in a database of valid identification cards.

Further, in some embodiments, processor 321 and database 322 may be configured to adapt to new data types. For example, in some embodiments, the administrators of database 322 may periodically update database 322 with new data associated with new entities (e.g., states, government organizations, or corporations). In other embodiments, processor 321, may be configured to update database 322 based on new data received from entities as the entities post new information (e.g., as a state releases a new type of identification card).

In other embodiments, processor 321 and database 322 may be configured to analyze received data that is not associated with a known type, and based on patterns of other received data, make a determination about the received data. For example, in one embodiment, processor 321 and database 322 may be configured to compare the encoding to known encoding types and thus determine that the encoded data is associated with North Carolina. The processor 321 and database 322 may be configured to further determine that some component of the encoding or encryption is incorrect, for example, because the person who set up the multidimensional code for the drivers' licenses in a jurisdiction (e.g., a state or county) used the wrong type of encoding. Based on this determination processor 321 may update database 322 with new information about this jurisdiction (e.g., the state or county), to thus enable processor 321 to use database 322 to determine data associated with that jurisdiction in the future. In still other embodiments, computing device 310 and server 320 may comprise additional components, such as additional memory and processing components or network components configured to provide faster or more convenient access via access network 330.

In some embodiments, the parsed data may be stored on the server 320. In some embodiments, this information may be used for future processing and authentication. For example, in some embodiments, a user may not be able to purchase more than a certain amount of age-restricted material (e.g., no more than one e-cigarette) within a set time period (e.g., one-day, one-week, one-month) to prevent a user from distributing them. Further, in some embodiments, the server 320 may store the total amount of an age-restricted material purchased by the user. In some embodiments, this information may be used to restrict the user's access to additional amounts of an age-restricted material. For example, one user may not be able to purchase over a certain quantity of the age-restricted material in a set time period. In still other embodiments, the user's age, the total amount of a substance the user has purchased, and the time since the user's last purchase may all be used together to determine whether the user can purchase more of the age-restricted material. In still other embodiments, the server may be configured to determine whether the user is on a no sell list, and, if so, prevent authorization of a purchase of age-restricted material.

Turning now to FIGS. 4A and 4B, FIGS. 4A and 4B comprise images 400 and 450 of data encoded on the back of drivers licenses from two different states. As shown in FIGS. 4A and 4B, the data is encoded using PDF-417. As discussed above, PDF-417 is a stacked linear barcode format. PDF stands for Portable Data File. The 417 signifies that each pattern in the code consists of 4 bars and spaces, and that each pattern is 17 units long.

In some embodiments, data encoded using PDF-417 may further comprise some type of compression or encryption. These types of encryption and compression are applied irregularly amongst jurisdictions such as Federal and State organizations. The present disclosure comprises a database that takes into account these differences and is usable for all jurisdictions. Further, in some embodiments, additional data may be encoded into the identification card. For example, in Florida some information associated with the driver may be embedded into the driver's license number. Thus, in some embodiments, a database associated with Florida driver's licenses may be useful only if it is designed to store this information.

Turning to FIG. 4C, FIG. 4C illustrates an example embodiment of the front face of an identification card 460. As shown in FIG. 4C, the identification card is an example similar to many states' driver's licenses and includes a picture as well as written information identifying the holder of the driver's license. FIG. 4D shows the reverse side 470 of the identification card 460. As shown in FIG. 4D, the identification card includes a PDF-417 label (e.g., labels 400 or 450 described above). In some embodiments, this label may comprise all or some part of the data on the front of the identification card. Further, in some embodiments, rather than being on the back of the card, the label may instead be located on the front. For example, some military identification cards (e.g., CAC cards) include a label on the front of the card. Some of these cards further include additional passive data-sources, such as ICC, SmartCards, RFIDs, NFCs, magnetic strips, or QR Codes. In some embodiments, rather than a PDF-417 label, the driver's license may instead comprise one of these other types of passive data-sources. Embodiments of the present disclosure may use similar technology to capture and decode data stored in these additional types of passive data sources. Further, In some embodiments, the identification card may comprise an electronic identification card, e.g., an electronic ID stored in a computer associated with the user, e.g., stored in an application on the user's mobile device. In some embodiments, such an electronic identification may comply with ISO/IEC CD 18013-5.

Illustrative Methods for Point of Sale Age Verification

FIG. 5 is a flowchart showing an illustrative method 500 for point of sale age verification. In some embodiments, the steps in flow chart 500 may be implemented in program code executed by a processor, for example, the processor in a general purpose computer, mobile device, or server. In some embodiments, these steps may be implemented by a group of processors. In some embodiments the steps shown in FIG. 5 may be performed in a different order. Alternatively, in some embodiments, one or more of the steps shown in FIG. 5 may be skipped or additional steps not shown in FIG. 5 may be performed. The steps below are described with reference to components described above with regard to the systems described above with regard to FIGS. 2A, 2B, and 3.

The method 500 is described with regard to image capture of a passive data source (e.g., of an image of a multidimensional bar code). However, the steps below are equally applicable to processing data extracted from other types of passive data sources. For example, these method steps may be applied to capturing data from a magnetic code (e.g., a magnetic strip), an RFID, NFC, a SmartCard, an Integrated Circuit Card (ICC) or some other type of passive data. Further, in some embodiments, the methods described below may be used to extract data appearing as printed text on the front of an identification card. In such an embodiment the processor 202 may be configured to perform an optical character recognition (OCR) of this text.

The method 500 begins at step 502 when processor 202 receives a scanner signal from scanner 218. As discussed above, scanner 218 may comprise one of a plurality of devices configured extract data from a passive data source (e.g., a barcode or other information printed on an identification card). In one embodiment, scanner 218 may comprise a camera configured to capture an image of the front or the back of an identification card. In some embodiments, the image may comprise an image of machine-readable data encoded in an identification card (e.g., on the back of the identification card). In some embodiments, the machine-readable data may comprise a multidimensional encoding, such as data encoded using PDF-417. In other embodiments, the image may comprise an image of text printed on the front or the back of the identification card. In still other embodiments the scanner 218 may comprise a scanner configured to scan other types of passive data sources, e.g., a magnetic code (e.g., a magnetic strip), an RFID, NFC, a SmartCard, an Integrated Circuit Card (ICC) or some other type of passive data.

Next processor 202 determines a type of encryption associated with the scanner signal 504. In some embodiments, determining the type of encryption may comprise determining a type of encoding associated with the scanner signal or determining that the scanner signal is not encoded or encrypted. For example, in some embodiments, determining a type of encryption may comprise determining how data is encoded, e.g., encoded in a matrix barcode such as a QR code, bar code, or multidimensional bar code encoded in PDF-417. Further, in some embodiments, determining a type of encoding may comprise determining a type of scanner, e.g., determining that the scanner signal is received from one or more different types of scanners 218, e.g., scanners configured to detect information embedded in one or more of an image, a magnetic code (e.g., a magnetic strip), an RFID, NFC, a SmartCard, an Integrated Circuit Card (ICC) or some other type of passive data. In still other embodiments, the type of encryption may be determined by processor 321 on a server connected to computing device 201 via a network connection.

At step 506 the processor 202 extracts known data elements from the scanner signal. For example, the processor may be configured to extract data elements such as e.g., the name, date of birth, address, driver's license number, height, weight, state, county, race, organ donor status, issue date, expiration date, driver restriction, class of vehicle, passport information, criminal record information, or any other information stored based on the scanner signal. The processor 202 may extract this information by comparing the scanner signal to data stored in a local data store. Alternatively, the processor 202 may execute algorithms to extract certain encoded data from the scanner signal. In still other embodiments, known data elements may be determined by processor 321 on a server connected to computing device 201 via a network connection.

Then at step 508 processor 202 transmits data associated with the scanner signal to a server 320. In some embodiments, processor 202 may compress data prior to transmission, e.g., the processor 202 may perform one or more compression algorithms to reduce network overhead and upload time in transmitting data associated with the scanner signal. Processor 202 may use network 210 to transmit the data. As discussed above, network 210 may comprise any type of wired and/or wireless network available to computing device 201. In other embodiments, processing the image data may comprise extracting known elements from the image. For example, in some embodiments, the image may comprise non-encrypted PDF-417. In such an embodiment, processor 202 may extract available known data from the image. For example, in some embodiments, the processor 202 may resize the image to 640×480 pixels, transform the image to 24-bit grayscale with a quality of 80%, and convert the image to Base64 string representation.

Processor 321 on server 320 may process the scanner signal to extract data from the scanner signal. Alternatively, in some embodiments, the processing may occur on processor 202 local to computing device 201. In some embodiments, processing the scanner signal may comprise determining information about the scanner signal, e.g., a type of encoding or encryption type associated with the scanner signal. In some embodiments, processing the data may comprise comparing the data to a database. In other embodiments, rather than performing a line-by-line comparison to a database, the server may instead use a series of algorithms developed based on previous cards to determine the data. For example, the server may comprise a database 322 of data associated with identification cards. The server may further comprise a series of algorithms configured to determine information about identification cards.

In some embodiments, these algorithms may have been developed using the data stored in database 322. In some embodiments, these algorithms may enable the server to quickly determine identification data. For example, the server may use algorithms and logic to quickly determine the TIN Number associated with the card. Further, once the IIN number is identified, the server may use low overhead string functions to perform a lookup in a specially formatted string that contains all of the applicable values. In some embodiments, this may comprise using a Supertanker String Lookup technique during the data discovery process. These may comprise low overhead string functions to perform a lookup in a specially formatted string that contains all of the applicable values. For example, enclosing the ID Issue State/Province in dashes “-” and looking for the index of its position in the following string: “-BC-, -MB-, -NF-, -PO-, -SK-, -ON-, -NS-, -NB-, -PE-”. In some embodiments, if the index is greater than zero, then the country of origin is Canada. Another example, putting a dash in front of the TIN and looking for the index of its position in a string like the following would return the corresponding state if valid: “-636033AL, -636059AK, -636026AZ, -636021AR”. In both of the above examples, the resources required to find the position of a string within another are much lower than doing a lookup in a table or other data structure.

Further, in some embodiments, processing the image data comprises determining that there is enough captured data to start the process. In some embodiments, processing may also determine whether the data was extracted from a magnetic stripe (e.g., via swiping a reader rather than a captured image) or a barcode. In some embodiments, processing the data may further comprise replacing any invalid binary characters and standardizing on the Track Sentinels. In some embodiments, processing the data may further comprise checking binary data points to determine if any information is encrypted (e.g., if the data comprises an encrypted driver's license or identification card). In some embodiments, the processing may further comprise replacing any invalid binary characters and determining the type of data (e.g., driver's license, military identification, passport, or some other data type).

Processing the scanner signal enables data associated with the scanner signal to be determined. In some embodiments, determining the data associated with the scanner signal comprise parsing the data to determine the stored information, e.g., the name, date of birth, address, driver's license number, height, weight, state, county, issue date, expiration date, or any other information stored in the encoded data. In some embodiments, this parsing process may comprise identifying and consolidating the field separators and delimiters in the multidimensional code, and identifying the name parts, taking into account the variations based on state/province, and intelligently recognizing which parts of the name are provided.

In some embodiments, the parsed data may be stored on the server 320. In some embodiments, this information may be used for future processing and authentication. For example, in some embodiments, a user may not be able to purchase more than one device within a set time period (e.g., one-day, one-week, one-month) to prevent a user from purchasing multiple age-restricted devices (e.g., from multiple points of sale) and distributing them (e.g., to underage users). Further, in some embodiments, the server 320 may store the total amount of an age-restricted material purchased by the user. In some embodiments, this information may be used to restrict the user's access to additional amounts of an age-restricted material. For example, one user may not be able to purchase over a certain quantity of the age-restricted material in a set time period. In still other embodiments, the user's age, the total amount of a substance the user has purchased, and the time since the user's last purchase may all be used together to determine whether the user can purchase more of the age-restricted material.

Then at step 508, server 320 transmits a data signal associated with the data extracted from the scanner signal. In some embodiments, this data signal comprises information associated with the age or identity of the user who scanned the identification card. Further, in some embodiments, this data includes whether the user is authorized to purchase age-restricted material 116, e.g., the user is over a certain age and had not purchased more than a certain quantity of age-restricted material within a certain time period.

At step 510, the computing device 201 receives the data signal from the server 320. Then at step 512, the computing device 201 transmits a verification signal to a point of sale device 112. In one embodiment transmitting the verification signal may comprise displaying a second passive data source comprising a verification code and configured to be scanned by the point of sale device 112. For example, in such an embodiment, the internet enable device 106 may display a machine readable code (e.g., a barcode) configured to be scanned by a scanner on the point of sale device 112. In some embodiments, such a machine readable code may comprise one or more of: a matrix barcode such as a QR code, bar code, or multidimensional bar code encoded in PDF-417. This machine readable code comprises data indicating that the user associated with the identification card 102 is authorized to purchase age restricted material 116. In another embodiment transmitting the verification signal may comprise displaying a textual verification code (e.g., an alphanumeric code) configured to be entered by a user into the point of sale device 112. In still another embodiment, transmitting the verification signal may comprise transmitting a verification signal to the point of sale device 112 network interfaces 110 and 114, e.g., via wired or wireless data transmission. For example, such a signal may be transmitted via one or more of a Ethernet, USB, microUSB, Firewire, IEEE 1394, and/or wireless interfaces such as IEEE 802.11, Bluetooth, Near Field Communication, RFID, and/or radio interfaces for accessing cellular telephone networks (e.g., transceiver/antenna for accessing a CDMA, GSM, UMTS, or other mobile communications network(s)).

The verification signal is required to allow point of sale device 112 to authorize and complete a sale of the age-restricted material 116 to the user associated with the identification card 102. Further, in some embodiments, the point of sale device 118 and/or the internet enabled device 106 may transmit data associated with the transaction to a remote database that stores information associated with purchases of age-restricted material 116. This information may be used in future sales transactions, e.g., to deny sale of an age-restricted device 251 to a user who has recently purchased another age-restricted device, thus preventing a user from purchasing a larger number of age-restricted devices 251 and distributing them.

Turning now to FIG. 6, which is a flowchart showing an illustrative method 600 for point of sale age verification. In some embodiments, the steps in flow chart 600 may be implemented in program code executed by a processor, for example, the processor in a general purpose computer, mobile device, or server. In some embodiments, these steps may be implemented by a group of processors. In some embodiments the steps shown in FIG. 6 may be performed in a different order. Alternatively, in some embodiments, one or more of the steps may be skipped or additional steps may be performed. The steps below are described with reference to components described above with regard to the systems described above with regard to FIGS. 2A, 2B, and 3.

At step 602 an point of sale device 112 receives an verification signal from internet enabled device 106. The verification signal was determined based on scanning a passive data source and extracting data from the passive data source as described in the embodiments above.

At step 604 the point of sale device 112 authorizes sales transaction allowing a user associated with identification card 102 to complete the transaction purchasing age-restricted material 116.

In other embodiments, the database of data associated with identification card data may be sold to application or web page development companies. In other embodiments, only portions of the database may be sold or made available, e.g., only the segment of the database associated with a state, region, or government entity. In other embodiments, algorithms developed to determine identification data associated only a certain region may be made available.
